ELEVATOR-CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 377,751, dated Eebruaryl4, 1888.

Application filed August 2'1, 1887. Serial No. 248,014. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN Thus, a citizen of the United States, residing in Chicago, in the county of Cook, in the'State of Illinois, have invented a new and useful Improvement in Elevator-Carriages for Passenger-Elevators, of which the following is a specification.

My invention relates to elevator-carriages in which 'a central passenger-chamber is surrounded on three sides and at top and bottom with an air-chamber, my object being to provide a safe elevator-carriage so constructed that an accident to the rope or hoisting device will not injure the passengers in case the elevator-carriage drops in the shaft. I attain this object by means of the devices shown in the accompanying drawings, in which- Figure l is. a vertical sectional view of the elevator-carriage. Fig. 2 is a horizontal sectional view of the elevator-carriage.

Similar letters'refer to similar parts throughout the several views.

Within an elevator-shaft, A A A A, travels an elevator-car, B, of suitable material,and so close to the sides of the shaft that there is just room enough for the elevator to ascend and descend in the shaft without scraping the sides of the shaft. Within the outer shell of the elevator-carriage B, I make a central chamber, E, and from the walls of the carriage B, I make partition-walls D and D, which extend out and support the central chamber, E. The

' partitions D and D, being united with the ment.

walls of the central chamber, E, form a number of compartments, '0, which extend along the sides of the central chamber, E, and unite at the top in a single chamber or compart- E, I make a chamber, G, which extends to the side walls of the central chamber. This chamber G at the bottom is perforated with a num- The partitions D and D act as braces ber of ho1es,a,which communicate with the air in the elevator-shaft, as do the compartments or chambersO in the sides of the elevatorcarriage.

Having thus described the parts of my invention, I now proceed to explain its operashaft A the air in the shaft A and'in'the space or compartment chambers O and G becomes more and more compacted and serves as an elastic cushion, upon which the elevator-carriage gradually comes to rest, thus preventing a sudden jar or thump at the bottom of the ,shaft.

I am aware that prior to my invention airtight elevatorshafts have been provided with a close-fitting carriage, whereby an air-cush:

ion is formed at the bottom of the shaft, and

I do not therefore lay claim to the use of an air-cushion in the broad sense; but

What I do claim, and desire to secure by Lettral chamber, E, the air chambers or compartments O, the compartment G, having the holes a and the partitions D and D, all arranged 2 and operating substantially as set forth and described.

2. In an elevator-carriage, the combination of a shaft, A, with a carriage, B, having the central chamber, E, and air chambers or compartments O and G, all arranged and operating substantially as set forth.
